hello everyone, i have a problem on split Tunneling on ASA when using L2TP over ipsec.
here is the info and request:
1. we have 4 subnet in our company: 10.0.0.x ; 10.0.1.x ; 10.0.2.x and 10.0.3.x
2. our colleagues want to remote access via L2TP dialup VPN (integrate with windows).
3. the vpn client need access all 4 subnet via vpn, BUT using their own ISP boardband to access internet.
here is my issue: i can access all office sunbet via VPN but cannot using my ISP boardband to access internet.
here is my configure:
ciscoasa# sh run
